EDWARD H. SHOLAR AND WALTER W. PAGE, OF CHATTANOOGA, TENNESSEE, AS-SIGNORS TO THE VOLUNTEER DISC PLOW 00., OF GEA'ITA'NOOGA, TENNESSEE.

DISK PLOW.

To all whom it may concern:

Be it known that we, EDWARD H. SHOLAR and lVALTER XV. PACE, citizens ofthe United States, residing at Chattanooga, in the county of Hamiltonand State of Tennessee, have invented a new and useful Disk Plow, ofwhich the following is a specification.

The general object of the present invention is to provide a disk plow ofextremely simple and inexpensive construction, in which all unnecessaryparts are eliminated, and in which the necessary adjustments areeffected by mechanism of very simple character and maximum efficiency.Subordinate to these general objects are certain specific objects, themost prominent of which are First, to provide a novel disk mountingwhich will enable the disk to be turned more or less to the land, or inother words, adjusted as to its horizontal angle to the line of draft,which will also enable the disk to be adjusted toward and from theperpendicular plane, and at the same time either elevated or depressedrelative to the beam, according to the character of the soil beingworked, and which will also enable the disk to be vertically adjustedwithout a change of either its horizontal or vertical angle. So far asthis feature is concerned, the present application is a division of theco-pending application, Serial No. 328,645, filed July 31, 1906.

Second to provide novel means for mount ing the scraper so that saidscraper is readily adjustable to properly cooperate with the disk nomatter in what relation the latter is positioned.

Third, to provide means whereby a plurality of beams or beam sectionsmay be secured together to provide a gang plow, the different sectionsor members being readily interchangeable.

An embodiment of the invention that is at present considered thepreferable one is illustrated in the accompanying drawings, whereinFigure 1 is a plan view of the plow. Fig. 2 is a side elevation of thesame. Fig. 3 is a sectional view of the disk and its mounting. Fig. 4 isa similar view with the parts adjusted to present the disk in a morenearly perpendicular plane and with said disk slightly elevated. Fig. 5is also a sectional view showing the parts adjusted to likewiseSpecification of Letters Patent.

Serial No. 388,673.

present the disk in a more nearly perpendicular position to slightlydepress it. Fig. 6 is a modified form of disk mounting simplified, buthaving somewhat less range of adjustment. Fig. 7 is a view of anothermodification, showing a still simpler disk mounting. Figs. 8, 9, 10 and11 are still further modifications of the mounting for the disk. Fig. 12is a detail sectional view showing the adjustable mounting for thescraper, said mounting being illustrated in elevation. Fig. 13 is asectional view therethrough. Fig. 14 is a detail sectional view on theline 1 1-14 of Fig. 13. Fig. 15 is a horizontal sectional view throughthe coupling between the beam members, or sections. Fig. 16 is a bottomplan view of the same.

Similar reference numerals designate corresponding parts in all thefigures of the drawings.

In the embodiment illustrated, the frame of the plow consists of beammembers or sections 17 having front and rear end portions 18 and 19disposed in obtuse angular relation to their middle portions. The frontend portions 18 are preferably disposed in alinement, as illustrated inFig. 1, and the beam sections or members are connected by a coupling 20.As shown particularly in Figs. 1, 15, and 16, this coupling consists ofa cap plate 21 having depending flanges 22 and 23, the flanges beinglocated inside the margins of the cap plate and disposed in angularrelation. The flange 23 moreover consists of angularly disposedportions, as shown. The flange 22 is disposed alongside the frontportion 18 of the rear beam section or member, and is secured thereto bybolts 2% that pass through said flange, and through openings 25 in thebeam member. A sufficient number of openings is provided to per mit theadjustment of said beam member, as will be evident by reference to Fig.15. The other flange 23 is located alongside the intermediate portion 17of the front beam, and the adjacent portion of the rear end 19 of saidbeam, and clamping bolts 26 are passed through the beam and flange.Thus, the beam sections or members are effectively secured together, butthey may be separated, and single plows formed therefrom, as will beevident. Moreover while two members are illustrated in the presentembodiment, it

will be evident that any desired number may be employed.

Secured to the front end 18 of the front beam member or section is abracket 27 formed with an upright guide 28 and a beveled segment 29. Theguide is vertically movable upon a post 30 supported by a front furrowwheel- 31 in any suitable manner. Fulcrumed upon the lower portion ofthe segment 29 is a front frame adjusting lever 32 having an angularlydisposed forwardly extending end or arm 33 connected to the post 30 by alink 34. The lever may be swung in an obvious manner to adjust the frontend of the frame vertically, and is retained in its adjusted positionsby the usual spring latch arranged to engage the segment.

A rear bracket 36 is bolted to and extends beyond the rear end of therear beam mem ber 17, and is provided at its ends with a verticallydisposed bearing sleeve 37 and a seat spring socket 38. The sleeve 37constitutes a bearing for the vertically disposed journal 39 of atrailing crank axle 40, on which is journaled a rear furrow wheel 41. Alatch 42, mounted on the bracket and operated by a conveniently locatedtreadle 43, serves to normally lock the axle against its swingingmovement. This mechanism, however, constitutes the subject-matter of thecopending application, to which reference has already been made, andneeds no detailed description. A seatspring 44 has its lower end locatedin the seat 38, and secured by a bolt 45, and a seat 46 is mounted onthe upper end of the spring.

To the central portion of the rear beam member or section is bolted aland wheel bracket 47 in which is journaled the swing ing axle 48 of aland wheel 49. This axle is adjusted with respect to the frame by alever 50 secured to the axle and retained in its adjusted positions bythe usual spring latch 51 engaging a toothed segment 52 fixed withrespect to the bracket 47.

To the front end of the foremost beam section or member is bolted adraw-bar attaching plate 52 to which is pivotally connected, asindicated at 53, a draw-bar 54 by means of which the draft animals arehitched to the plow. It is desirable to dispose the draw-bar in variousangular positions with respect to the line of draft, and for thispurpose, the plate is provided with a series of bolt holes 55 designedto receive a holding bolt 56 extending through the bar 54. Said bar maytherefore be swung upon its pivot, and secured in any desired positionby the bolt 56.

The disks 57 are mounted on the rear portions of the beam members orsections, and as usual, are provided with spindles 58, which rotate inboxings 59 located at the lower ends of vertically disposed standards(30. Each standard is rotatable in a disk supporting bracket 61 secured,in a manner to be explained, to the rear portion 18 of each beam. Thedisk standard is provided with an angular upper end 62 and a threadedextremity 63, the angular portion being designed for the attachment ofan arm 64 retained upon the standard by a nut 65 screwed upon theextremity 63 and bearing against a washer 66 interposed between the nutand angular portion. At a point opposite the arm 64, the bracket 61 isprovided with a rigid lug G7, and through this lug and arm is passed anadjusting screw 68 equipped with nuts 69 which clamp the arm and lug,and prevent their relative movement, as clearly shown in Fig. 1. Byturning the nuts 69 in the proper direction, the arm 64 may be movedtoward or from the lug (37, thus rotating the standard 60 for thepurpose of adjusting the angular relation of the disk with respect tothe line of draft, or in other words, for the purpose of adjusting thedisk to take more or less land. It will be noted that this character ofadjusting means permits an exceedingly fine adjustment of the disk or amore extended adjustment thereof if desired. Moreover the disk adjustingmeans also constitutes retaining means for the disk, and it is thereforeunnecessary to operate a separate locking device, in order to hold thedisk after the adjusting mechanism has been operated to set the disk atthe proper angle. In addition to this adjustment of the disk withrespect to the line of draft, the mounting also comprehends meanswhereby the vertical inclination of the disk may be changed and saiddisk simultaneously raised or lowered, also means for adjusting the diskvertically without any change of its angular disposition either withrespect to the grounds or to the line of draft.

In order to attain these ends, the disk supporting bracket 61 comprisesthree bracket sections or members 61 (31", and (31, normally occupyinghorizontally alined positions, as illustrated in Fig. 3 and retained inrigid relation with each other and with the beam by bolts 70 passedthrough slots 71 in the bracket members, and also through the rearportion 19 of the beam. The bolts are retained by nuts 72 screwedthereon and bearing against a rear side of the beam. The slots 71 are ofsufficient extent to permit relative adjustment of the bracket members.The opposite sides of the central member 61 are reversely curved, asshown in Figs. 3 and 4, and engage the reversely curved adjacent facesof the members 61 and 61 it being understood that the disk standard 60is journaled in the outer bracket member 61. The innermost bracketmember 61 is located against the side of the beam, the contacting facesof these elements being disposed vertically. The various faces of thebeam and bracket members are horizontally corrugated for the purpose ofinsuring their rigid engagement.

It is obvious that if it desired to adjust the disk vertically withoutchanging its angle, it is merely necessary to loosen the bolts andadjust the entire disk supporting bracket as a unit with respect to thebeam. If on the contrary, it is desired to shift the disk to a morenearly perpendicular position without depressing the same or with aslight elevation thereof, the desired end may be attained by looseningthe bolt and elevating the outer bracket member 61 with respect to thecentral member 61", as shown in Fig. 4. If it is desired to adjustthedisk to a more nearly perpendicular po sition and to simultaneouslydepress the disk, for the purpose of deepening the cut, this may be doneby adjusting the members (31 and 61" as a unit with reference to theinnermost member 61 as disclosed in Fig. 5. It will thus be seen thatthe peculiar form of the disk mounting not only provides for a widerange of adjustments both as to the horizontal and vertical angles ofthe disk but that it also provides for exceedingly fine adjustments. Thesame is obtained by simple and durable mechanism so that the disk may beadjusted with absolute accuracy to whatever position is best adapted tothe particular character of the soil being worked.

In Figs. t l1 inclusive, modified forms of the disk supporting bracketwhich fall within the scope of the invention are illustrated. Forinstance, in Fig. 6, the inner bracket is eliminated, and a member (31is interposed between the beam and the member (51. In this form of theinvention, the bracket is adjusted vertically on the beam, and the uppermember 61 is adjusted in the manner shown in Figs. l and 5. In Fig. 7,the member 61 is directly opposed against the modified form of beam 18the modification consisting in providing the beam with a curved facecorresponding to the contacting curved face of the bracket member. InFig. 8, a bracket member Gl similar to the member (31, but modified byreverscly curving its inner edge, is opposed to a modified form of beam18 having a convexly curved face opposed to the curved face of themember (31 In Fig. 9, the bracket member (31 is o) )osed to a member 61identical in construction with the member 61 shown in Fig. 3, butinterposed directly between the beam and the member (31. In Fig. 10, theouter bracket section 61 is modified by inclining its inner face and byinterposing between the said member and the beam, a member (31 havingits inner face opposed to the beam and its outer face inclined incorrespondence with the inner face of the member 61 In Fig. 11, theconstruction is the same as that shown in Fig. 2-3, except that themember (31 is integral with the beam. These seve 'al modifiedconstructions of the disk mounting are capable of substitution, for thatshown in Fig. 3, inasmuch as each possesses one or more of the novelcharacteristics of the construction first described, and which isperhaps the preferable form of mounting.

A scraper blade 73 cooperates with each disk, and in order that saidblade will effectively perform its function, regardless of theadjustment of the disk, a mounting for the scraper having a wide rangeof adjustment is essential. This mounting is preferably constructed asfollows. An upstanding bracket 74: has a lower offset end 75 bolted, asshown at 76 in a seat 77 formed on the outermost bracket member (31 andthe upper end of the bracket 74 is provider with an offset horizontallydisposed terminal 78. A convexed bearing head 79 is mounted on thehorizontal terminal 78, and is provided with depending ribs 80 thatembrace the same. A concaved bearing head 81 fits upon the head 79, andprovided with a longitudinal slot A holding bolt 83, passing through theterminal 78, the head 79, and the slot 82 has a threaded upper end onwhich a nut 84 is screwed. Consequently when this nut is tightened, itwill be evident that the head 82 will be held against movement, and indifferent positions while the bolt serves to secure all the parts to thebracket 'd. The concaved cap or head 81 is provided with an outstandingarm 85 terminating in an upright sleeve 86, and through this sleevepasses an upright stem 87 having the blade 73 secured to its lower end.A set screw 88, threaded through the sleeve, engages the stem, andserves to hold it against movement. This structure as will be evidentpermits an adjustment of the scraper blade so that it will properlycoope'ate with the disk when the latter is adjusted to different variouspositions, as above described.

From the foregoing, it is thought that the construction, operation, andmany advan tages of the herein described invention will be apparent tothose skilled in the art, without further description, and it will beunderstood that various changes in the size, shape, proportion, andminor details of construction, may be resorted to without departing fromthe spirit or sacrificing any of the advantages of the invention.
